Thanks for the comments. The prices that people are suggesting for slide scanners is making me think again. I did not feel the cost of buying a dedicated scanner would be worthwhile and also I was not sure if I wanted to devote the time, but it sounds as if they are also fairly quick.

A 5 MPx scanner would probably be fine as I am not expecting to produce quality prints, rather mainly be able to display them on the computer or on a digital photo frame.

As for touching up or image enhancement. I see some come with software for that purpose, but it is not a lot of use as I am on Linux. I do have the Gimp image manipulation programme on my computer, though, which will almost certainly do the job should I need it.
